Sql 如何在不同的服务器之间创建相互连接的两个数据库

编辑：例如，如果一台服务器关闭，另一台服务器具有相同的数据，我将能够使用它

我想要实现的示例：

服务器1->数据库示例

INSERT INTO DBExample (idExample, nameExample) VALUES (123, 'Example');

SELECT * FROM DBExample;
+-----------+-------------+
| idExample | nameExample |
+-----------+-------------+
|       123 | Example     |
+-----------+-------------+

SELECT * FROM DBExample;
+-----------+-------------+
| idExample | nameExample |
+-----------+-------------+
|       123 | Example     |
|      1234 | Example2    |
+-----------+-------------+

服务器2->DBExample2

SELECT * FROM DBExample2;
+-----------+-------------+
| idExample | nameExample |
+-----------+-------------+
|       123 | Example     |
+-----------+-------------+

INSERT INTO DBExample2 (idExample, nameExample) VALUES (1234, 'Example2');

SELECT * FROM DBExample;
+-----------+-------------+
| idExample | nameExample |
+-----------+-------------+
|       123 | Example     |
|      1234 | Example2    |
+-----------+-------------+

反之亦然：

服务器2->DBExample2

SELECT * FROM DBExample2;
+-----------+-------------+
| idExample | nameExample |
+-----------+-------------+
|       123 | Example     |
+-----------+-------------+

INSERT INTO DBExample2 (idExample, nameExample) VALUES (1234, 'Example2');

SELECT * FROM DBExample;
+-----------+-------------+
| idExample | nameExample |
+-----------+-------------+
|       123 | Example     |
|      1234 | Example2    |
+-----------+-------------+

服务器1->数据库示例

INSERT INTO DBExample (idExample, nameExample) VALUES (123, 'Example');

SELECT * FROM DBExample;
+-----------+-------------+
| idExample | nameExample |
+-----------+-------------+
|       123 | Example     |
+-----------+-------------+

SELECT * FROM DBExample;
+-----------+-------------+
| idExample | nameExample |
+-----------+-------------+
|       123 | Example     |
|      1234 | Example2    |
+-----------+-------------+

由于这是SQL Server，请查看双向事务复制或对等复制

它们是链接的服务器吗？您可以创建一个视图，该视图合并两台服务器的表：该视图属于dba.stackexchange.com，但这里有一个开始：
